Hi there,

You need some way to save the state of the form so you can do a server-side redirect.

For server state, you can use:

- Session state. Store the fields in the session in page 1, and reload them again when the page is requested

- Cookies - work similar to session state but are stored client side and are accessible at the server

- Save the data in the database and reload it when the page is requested again.

In other words, lots of options to choose from. You may want to Google a bit for each of these options to see their (dis)advantages.

Alternatively, you can use JavaScript's history.go(-1) to take the user back the previous page.

Cheers,

Did you follow my suggestion to Google a bit on ASP.NET Session state? It's quite a broad topic and a lot has been written about it. So, you're better off reading some stuff yourself so you get a good understanding of what it is and how to use it.

Hi there,

Not sure I understand what you're asking. is this code from the first page (e.g. how you pass data to the "confirm" page) or is this your attempt to pass the values back to the first page?

Either way, the idea should work. But, depending on your current setup, on Page 2 you shouldn't get the value from a TextBox but from a query string. E.g.:

Code:

Protected Sub Goback_Click(ByVal sender As Object, ByVal e As EventArgs) Handles GoBack.Click
        Response.Redirect("Page1.aspx?name=" + Request.QueryString.Get("Name"))
End Sub

Then in Page1 you can try to prefill the text box from the query string:

Code:

 
If Not String.IsNullOrEmpty(Request.QueryString.Get("Name"))
  TextBox1.Text = Request.QueryString.Get("Name")
End If

Hope this helps,

Imar

You can create your own collection class and store it in the session and when the page is loaded, you can check whether the session is null or not and bind the data from your session to the controls by converting it to the collection object too...

Code:

public class Person
{
public string FirstName
{get; set;}

public string LastName
{get; set;}
}

In your Page's Code Behind:

Code:

partial class Page1:Web.Form
{

public Person myPerson
{get; set;}

protected void button1_click(object sender, EventArgs e)
{

Person p=new Person();
p.FirstName=txtFirstName.Text;
p.LastName=txtLastName.Text;

Session["Person"]=p;

}

protected void Page_Load(object sender, EventArgs e)
{

if(Session["Person"]!=null)
{
myPerson=(Person)Session["Person"];

txtFirstName.Text=myPerson.FirstName;
txtLastName.Text=myPerson.LastName;

}
}
}

Happy Coding.
